McCullough Charged on Five Criminal Counts

Sycamore, IL -- Illinois State Police and the DeKalb County State’s Attorney’s Office announced a Grand Jury indictment against Jack Daniel McCullough, (aka John Tessier). McCullough/Tessier was officially charged in DeKalb County with one count of child sexual assault, and four counts of indecent liberties with a child.

The victim told Illinois State Police investigators that she was raped by Jack McCullough when she was 14 years of age in Sycamore, Illinois.

“Sadly, we have another victim, and for the families of all victims, the pain never goes away,” said ISP Director Hiram Grau. “The ISP Special Agents who have been tirelessly working this case will continue to be unrelenting in their efforts to find justice, closure, and peace for the Sycamore community,” Grau added.

Based on the new information received during the investigation, the DeKalb County State’s Attorney, Clay Campbell, has decided to officially charge McCullough/Tessier with these charges. A Grand Jury was convened and indicted McCullough on all five counts.

McCullough was charged in July with the murder, kidnapping and abduction of an infant, and he remains in custody at the DeKalb County jail on a $3M bond.
